@Laxfm y as ya screw` in diaphram 11, said pressure of fastening through 'i easily removed tating the orifice. closer upon its axis Vthe studs 6 are passed into'the narrow end of the slots 7 and the nuts 8 effectively locked over the body 1 of the orifice closer without having to beu removed orreplaced, and the orifice closer locked or fastened to the reservoir. D f r The clamping of the cup shaped cover 2 overfthe'gaslret 9 and the orifices 3 and 4 lis attained by-means of pneumatic or hydraulic, pressure in being controlled by the valve'12 and transmitted to the cover cup 2v through the plate 13. The pressure exerted against the cover plate 14 is counteracted by the studs 6 or other means thev body 1 of the orifice closer, and the orifice closer is thereby held against receding from the reservoir 5 and the *coverv cup 2 firmly .clamped over the orifices 3 and 4 and said orifices are effectively closed.

wWhereas, it may now be assumed that the orifice closer is fastened securely to the receptacle 5 and that the orifices 3 and 4 are sealed against the ingress or egress of gases or liquids except by way of the valves 15 and 16, it is evidentv that we have complete control of the passage of gases or liquids under pressure through the orifices?) and 4 by means of the valves 15 and 16. 1n the specific case illustrated in Figs. 1 and 2, the valves 12, 15 and 16 aresupposed to be attached` to flexible hose not shown and which furnish a means of conveying the compressed agent to the orifice closer and receptacle. v

To release the orifice closer from the receptacle 5, the gas or liquid may bereleased from the receptacle 5 by means of the valves 15 and 16 which may be three way valves or by other means when necessary, after which the pneumatic or hydraulic pressure upon the ydiaphragm 11`may be relieved through a properly constructed valve 12 which we will assume to be a three way valve. l

Y'The orifice closer will then be left'loose on the studs V3l and maybe rotated back to its first position ,with the rstuds 6 in the large Vends of the slots 7 where it may be from the studs 6 andthe receptacle 5 without` the necessity of re-y moving nuts, bolts orsimilar fastenings.

- The diskor plate l13 isffastened to the cover cup 2 by means of a part 17 shown s l thisy specific case, but may beany similar 'means bolt or rivet. The part 17 should be and is to loe fastened tightly'into the cup coverv 2 but is left loose in the plate 13 so that plate 13 and cupcover 2 are free to move independently. Thus, after the pressure is applied come to rest with its top face parallel to the squarely and evenly upon may be the chamber 10 upon the of fastening, as av to diaphragmA 11, the plate 13 willY cover 2 will rest the face of the receptacle 5, although the means of fastening the orifice closer to the receptacle 5 may be such that the plane ofthe dia-V phragm 11 and the face of the receptacle 5 considerably out of parallel.

2 and 13 todiaphragm 11, and the cup This feature of fastening gether is of particular advantage as by said" means it is not rnecessary to have the means of fastening the orifice closer to the receptacle such that a plane verticall to the axis of the orifice closer will always be parallel tothe face of thereceptacle over which it is clamped.

rIherefore, in the specific fastening illustrated in Figs. 1 and 2, it is neither necessary to have the three studs 6 of the same length,

nor lthe nuts 8 thereon screwed downto the same distance from the face of the res-V ervoir 5. I

1n Fig. 3 is shown the orifice closer withV bolts 18 as a means of attaching a cover plate 19 to the orifice closer. plate has oblong holes or slots in it similar to 7 in Fig. 1 to facilitate the removal and attaching of the cover plate 19, also an opening 20 as a means of fastening a valve for the'release of pressure exerted uponfa Vre ceptacle clamped between the plate 19 and the cupped cover' 2 ofthe orifice closer. The operation of attaching lor detaching the The cover y plate 19 is very similar to that of attaching c' or detaching the orifice closer as shown 1n Fig. 1. The bolts 18 are fastened solidly into the body 1 of the orificeV closer, and the plate 19'is attached by passing the heads of'bolts 18 throughptheflarge ends of slots in 19 similar to 7 and'then rotating vplate 19 so that bolts 18 will pass into the small ends of the slots and the heads of bolts 18 will be Jlocked over plate 19 and secure it to the orifice closer which may then .be operated as described in connection with Figs. 1 and 2, and pressures applied to a receptacle clamped between 19 and 2. Y

The projections 21, 22 and 23 serve in assisting in placing the different ports and Covers directly over the orifices which Vthey may be intended to cover and also in holding the parts in their proper places. The ribs 24 and 25 serve as a backing for the gaskets, which are necessarily narrow, and prevent them from blowing out while under pressure.4 I Y 'f ,In Fig. 4 is the orifice closer attached to a, valve 26 by means of a cover plate 27, and a plurality of hooks 28. A-nipple 29 forthe attaching of a valvevfor the releasing of pressures fin the valve l26 is shown. TheA hooks 28 arefpivoted on agpin 30 which .al. lows them tomove back while the valve"26l and theY plate 27 are being inserted, the hooks being automatically held "inward jby the springs 31, and having a means of being held from going so far inward as to allow springs 31 to drop out or hinder valve 26 and plate 27 from being easily inserted. Therefore, both ends of the valve may be wholly or partly c losed, and the passage of gases or liquids through it controlled bythe* valve itself, a valve attached to the nipple 29 and a valve attached to the cover cup 2 as shown in Fig. 1. The feature is that in testing valves, receptacles, etc., the orifice closer is easily and quickly attached or detached without the removal or replacement of nuts, bolts or similar fastenings'. The clamping being accomplished by pressure upon the diaphragm l1 and and the pressure being then transmitted to gaskets on one or both ends of the receptacle by means of the plate 13 and the cupped cover 2 and a means of fastening the orifice closer to the receptacle.

Similar to the arrangement shown in Fig. 4, the hooks 28 may be shortened, and the cupped cover 2 lengthened to allow the oriiice closer to be attached directly to a flange 32 by having hooks 28 hook over flange 32 instead of plate 27.

In reference to the valves 12, 15 and 16,' they are not a part of my invention, and any valves now in common use may be made use of. As many or as few valves may be used in connection with the cupped cover 2 as are necessary to furnish means Vof controlling the flow of gases or liquids through the number of orifices which it is necessary to cover in any specific case. Another commendable feature is the fact that the compressed gases or liquids are at no time eX- posed to working joints or joints which are liable to wear loose and cause leakage. Also the small space 10 between 11 and 14 which it is necessary to fill to operate the orifice closer makes the orifice closer very efficient in the use of the agent used to operate it.

The few parts and simplicity of construction make an orifice closer not liable to get out of order easily and which should be easy to maintain.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a reservoir, studs mounted on said reservoir, of an orifice closer including, a body, said body having slots therein, said slots being large at one end to receive said studs, a cover plate, the inner surface of said cover plate having a chamber formed therein, a diaphragm interposed between said cover plate and body, a cup-shaped cover for the orifice, a disk member, a screw having the head thereof loosely mounted vin said disk, the opposite end of the screw being rigidly secured to the cup-shaped member, gaskets mounted on said cup-shaped member, ribs formed on the member to retain the gasket, means for conducting liquid to said chamber under pressure, a valve mounted on said means for controlling the ingress and egress of the hydraulic fluid for controlling the pressure exerted on the diaphragm.
